I need help implementing in place turning animations for my full body first person controller.

Hello guys, am trying to make realistic full body first person controller (resident evil 7 like). I want to add in place turning animation, when a player moves the mouse left or right. I allready have a 2D freeform directional blend tree for my movements and I also have script that would handle the turning animation. But I don’t know what I should add in my animator to make the turn animation actually work. Could anyone help me?

this is my code:

private void HandleAnimations()
        {
            // Calculate velocity components for movement blend tree
            float velocityX = _input.move.x * _speed / MoveSpeed;
            float velocityY = _input.move.y * _speed / MoveSpeed;

            // Pass these values to the Animator for movement animations
            _playerAnimator.SetFloat("VelocityZ", velocityX, dampTime, Time.deltaTime);
            _playerAnimator.SetFloat("VelocityY", velocityY, dampTime, Time.deltaTime);


            // Check if character is moving
            bool isMoving = velocityX != 0 || velocityY != 0;

            // Calculate turn direction based on mouse movement only when idle
            float turnDirection = 0;
            if (!isMoving) // Only turn when idle
            {
                float mouseX = Input.GetAxis("Mouse X");
                if (mouseX > 0.1f) // You can adjust the threshold here
                {
                    turnDirection = 1; // Right turn
                }
                else if (mouseX < -0.1f)
                {
                    turnDirection = -1; // Left turn
                }
            }

            // Update the TurnDirection parameter and log it
            _playerAnimator.SetFloat("TurnDirection", turnDirection, dampTime, Time.deltaTime);
            Debug.Log("TurnDirection: " + turnDirection);
        }

in the screenshot you can see my animator
